Title: Electronic scanning antenna
Inventor: KITAJIMA KOICHI
IPC: H01Q3/26
Filed: 1989-07-19
Abstract: PURPOSE:To suppress the deterioration of the entire noise exponent without increasing the size of a device by switching a preamplifier being a component of a high output amplifier of a transmission system at the time of reception and connecting the preamplifier after a low noise amplifier of a reception system in order to increase the gain of a reception system of a transmission/reception module being a component of an electronic scanning antenna. CONSTITUTION:A high frequency signal at transmission is distributed to transmission/reception modules 2a-2n at a feeding circuit 4 through a transmission/reception changeover switch 5 and a phase shift according to the arrangement sequence of element antennas 1a-1n is set by a phase shift control signal with a phase shifter 21. The high frequency signal subjected to phase shift passes through a transmission/reception switch 25 and is amplified by a preamplifier 26 connected to a final stage amplifier 27 of a transmission system and the final stage amplifier 27 connected to the transmission system by a transmission/reception switching signal and radiated from the element antennas 1a-1n into space via the transmission/reception changeover switch 24. On the other hand, the preamplifier 26 being a component of the high power amplifier 22 is connected after a low noise amplifier 23 by using transmission/reception changeover switches 28, 29 at the time of reception. Thus, the gain of the reception system is increased and the deterioration in the noise exponent is suppressed without a large sized device.

Title: Direct junction of laser optical crystal
Inventor: SUGIYAMA RYO
IPC: H01S3/16
Filed: 1997-07-11
Abstract: PROBLEM TO BE SOLVED: To form a large high-quality laser optical crystal having uniform optical active-ion concentration, by performing chemical processing and high-temperature heat processing on a junction surface without adhesive. SOLUTION: A step 1 includes a step 11 of cleaning the junction surface and removing an natural oxide film by using mixed liquid of sulfuric acid and hydrogen peroxide, a step 12 of cleaning by using high-purity water, and a step 13 of cleaning the junction surface by using etchant appropriate to the material to remove the natural oxide film. A step 2 includes a step 21 of OH termination on the junction surface by using diluted sulfuric acid water and a step 22 of cleaning by using high-purity water. In a step 3, laser optical crystals are brought into contact in wet state in a high-clean atmosphere. In a step 4, the crystals in contact are dried in the atmosphere in unloaded state so as to remove excessive water between the surfaces in contact and form hydrogen junction.  After the hydrogen junction formation, in a step 5, heat processing is performed on the crystal surface within a vacuum or gas atmosphere at a temperature higher than that in step 4, to separate the water from the hydrogen junction, and to cross-link -O- remaining between the surfaces in contact, to establish direct junction of oxide crystals. Thus the high-quality large laser optical crystal is formed.
